(57) [Problem] To quickly and accurately detect an abnormality of a motor of an energy adjusting means provided in a power output device. A power output device includes: an engine; Outer rotor 32 coupled to crankshaft 56 of engine 50 and inner rotor 3 coupled to drive shaft 22 4, an assist motor 40 attached to the drive shaft 22, and a control device 80. The control device 80 controls the intake air amount and the fuel injection amount so that the energy represented by the product of the target rotation speed and the target torque is output from the engine 50, and controls the clutch motor so that the engine 50 is operated at the target torque. 30 Control. In such control, if the rotation speed of the engine 50 does not converge to the target rotation speed despite the normal operation of the engine 50, it is determined that an abnormality has occurred in the clutch motor 30. |
